Create a seperated fiq-params struct to pass all arguments. Signed-off-by: Markus Pargmann --- Notes: Changes in v7: - Fix init function signature for !CONFIG_SND_SOC_IMX_PCM_FIQ Changes in v6: - After rebasing onto Shawn's imx-pcm cleanups, the imx_pcm_fiq_params are now passed as function arguments instead of platform driver data. Changes in v3: - Using snd_dmaengine_dai_dma_data for dma_params after rebasing onto dmaengine cleanups. sound/soc/fsl/imx-pcm-fiq.c | 18 ++++++++++-------- sound/soc/fsl/imx-pcm.h | 15 +++++++++++++-- sound/soc/fsl/imx-ssi.c | 7 ++++++- sound/soc/fsl/imx-ssi.h | 1 + 4 files changed, 30 insertions(+), 11 deletions(-) diff --git a/sound/soc/fsl/imx-pcm-fiq.c b/sound/soc/fsl/imx-pcm-fiq.c index 310d902..3b2ba99 100644 --- a/sound/soc/fsl/imx-pcm-fiq.c +++ b/sound/soc/fsl/imx-pcm-fiq.c @@ -22,6 +22,7 @@ #include #include +#include #include #include #include @@ -32,6 +33,7 @@ #include #include "imx-ssi.h" +#include "imx-pcm.h" struct imx_pcm_runtime_data { unsigned int period; @@ -366,9 +368,9 @@ static struct snd_soc_platform_driver imx_soc_platform_fiq = { .pcm_free = imx_pcm_fiq_free, }; -int imx_pcm_fiq_init(struct platform_device *pdev) +int imx_pcm_fiq_init(struct platform_device *pdev, + struct imx_pcm_fiq_params *params) { - struct imx_ssi *ssi = platform_get_drvdata(pdev); int ret; ret = claim_fiq(&fh); @@ -377,15 +379,15 @@ int imx_pcm_fiq_init(struct platform_device *pdev) return ret; } - mxc_set_irq_fiq(ssi->irq, 1); - ssi_irq = ssi->irq; + mxc_set_irq_fiq(params->irq, 1); + ssi_irq = params->irq; - imx_pcm_fiq = ssi->irq; + imx_pcm_fiq = params->irq; - imx_ssi_fiq_base = (unsigned long)ssi->base; + imx_ssi_fiq_base = (unsigned long)params->base; - ssi->dma_params_tx.maxburst = 4; - ssi->dma_params_rx.maxburst = 6; + params->dma_params_tx->maxburst = 4; + params->dma_params_rx->maxburst = 6; ret = snd_soc_register_platform(&pdev->dev, &imx_soc_platform_fiq); if (ret) diff --git a/sound/soc/fsl/imx-pcm.h b/sound/soc/fsl/imx-pcm.h index 67f656c..cd8a796 100644 --- a/sound/soc/fsl/imx-pcm.h +++ b/sound/soc/fsl/imx-pcm.h @@ -32,6 +32,15 @@ imx_pcm_dma_params_init_data(struct imx_dma_data *dma_data, dma_data->peripheral_type = IMX_DMATYPE_SSI; } +struct imx_pcm_fiq_params { + int irq; + void __iomem *base; + + /* Pointer to original ssi driver to setup tx rx sizes */ + struct snd_dmaengine_dai_dma_data *dma_params_rx; + struct snd_dmaengine_dai_dma_data *dma_params_tx; +}; + #ifdef CONFIG_SND_SOC_IMX_PCM_DMA int imx_pcm_dma_init(struct platform_device *pdev); void imx_pcm_dma_exit(struct platform_device *pdev); @@ -47,10 +56,12 @@ static inline void imx_pcm_dma_exit(struct platform_device *pdev) #endif #ifdef CONFIG_SND_SOC_IMX_PCM_FIQ -int imx_pcm_fiq_init(struct platform_device *pdev); +int imx_pcm_fiq_init(struct platform_device *pdev, + struct imx_pcm_fiq_params *params); void imx_pcm_fiq_exit(struct platform_device *pdev); #else -static inline int imx_pcm_fiq_init(struct platform_device *pdev) +static inline int imx_pcm_fiq_init(struct platform_device *pdev, + struct imx_pcm_fiq_params *params); { return -ENODEV; } diff --git a/sound/soc/fsl/imx-ssi.c b/sound/soc/fsl/imx-ssi.c index a8362be..16ae16d 100644 --- a/sound/soc/fsl/imx-ssi.c +++ b/sound/soc/fsl/imx-ssi.c @@ -590,7 +590,12 @@ static int imx_ssi_probe(struct platform_device *pdev) goto failed_register; } - ret = imx_pcm_fiq_init(pdev); + ssi->fiq_params.irq = ssi->irq; + ssi->fiq_params.base = ssi->base; + ssi->fiq_params.dma_params_rx = &ssi->dma_params_rx; + ssi->fiq_params.dma_params_tx = &ssi->dma_params_tx; + + ret = imx_pcm_fiq_init(pdev, &ssi->fiq_params); if (ret) goto failed_pcm_fiq; diff --git a/sound/soc/fsl/imx-ssi.h b/sound/soc/fsl/imx-ssi.h index d5003ce..fb1616b 100644 --- a/sound/soc/fsl/imx-ssi.h +++ b/sound/soc/fsl/imx-ssi.h @@ -209,6 +209,7 @@ struct imx_ssi { struct snd_dmaengine_dai_dma_data dma_params_tx; struct imx_dma_data filter_data_tx; struct imx_dma_data filter_data_rx; + struct imx_pcm_fiq_params fiq_params; int enabled; };
